Yankee White is a security clearance given in the United States for personnel working with the President. It is considered to be equivalent or above "Top Secret" clearance. Obtaining such clearance requires, in part, a Single Scope Background Investigation (SSBI) by the Department of Defense. Contrary to popular lore, the Yankee White clearance given to personnel who work directly with the President is not a classification, but rather a type of background check.
Examples of those with a Yankee White include the Old Guard and the United States Navy Ceremonial Guard
"Yankee White" is also the name of the pilot episode of the television series Navy NCIS.
